Internet cap used up - complained and no feedback

We have recently been using up all our Cap on the internet - 50gig! in a small office with email and some internet searching. I felt this was far too much to be used with so little activity. It also interrupts our business with throttling of emails etc when the cap is reached.<br> I called and complained to Telkom and they could not help on their call centre, referring me to an email address - [Email Removed]<br> Having written to [Email Removed] on the 21st July, I am yet to have a response and now sit with the exact problem again for the last few days in the office - the only way to correct this is to purchase more Cap.<br> We changed the internet wifi passwords last month, withh only 2 people having access to this and this did not help.<br> <br> It is inconceivable that we use so much cap. Can Telkom tell me which ip addresses are using this cap? How can we control this better and see who is using the cap?<br> <br>
